Real-time high-resolution omnidirectional imaging platform for drone detection and tracking
Jean-Philippe Thiran, Selman Ergünay, Yusuf Leblebici, Vladan Popovic, Bilal Demir, Gökçen Nurlu
Drones have become steadily affordable, which raises privacy and security concerns as well as interest in drone detection systems. On the other hand, drone detection is a challenging task due to small dimensions of drones, difficulty of long-distance detec ...
SPRINGER HEIDELBERG2019Real-Time Computational Gigapixel Multi-Camera Systems
The standard cameras are designed to truthfully mimic the human eye and the visual system. In recent years, commercially available cameras are becoming more complex, and offer higher image resolutions than ever before. However, the quality of conventional ...
EPFL2016Multi-Camera Platform for Panoramic Real-Time HDR Video Construction and Rendering
Yusuf Leblebici, Vladan Popovic, Kerem Seyid, Ömer Cogal, Eliéva Arlette Pignat
High dynamic range (HDR) images are usually obtained by capturing several images of the scene at different exposures. Previous HDR video techniques adopted the same principle by stacking HDR frames in time domain. We designed a new multi-camera platform wh ...
Springer Heidelberg2016Near-Infrared High-Resolution Real-Time Omnidirectional Imaging Platform for Drone Detection
Yusuf Leblebici, Vladan Popovic
Recent technological advancements in hardware systems have made higher quality cameras. State of the art panoramic systems use them to produce videos with a resolution of 9000 x 2400 pixels at a rate of 30 frames per second (fps).(1) Many modern applicatio ...
Spie-Int Soc Optical Engineering2016A Real-time Multi-aperture Omnidirectional Visual Sensor Based on Interconnected Network of Smart Cameras
Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Hossein Afshari, Abdulkadir Akin, Kerem Seyid, Ömer Cogal
Centralized and multi-level implementations of the Panoptic omnidirectional multiaperture visual system were previously presented by the authors, relying on transmission of all camera outputs to a single central processing node for omnidirectional image an ...
Institute of Electrical and Electronics Engineers2015Real-Time Omnidirectional Imaging System with Interconnected Network of Cameras
Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Hossein Afshari, Kerem Seyid
The Panoptic camera is an omnidirectional multi-aperture visual system which is realized by mounting multiple imaging sensors on a hemispherical frame. In this chapter, we will present a novel distributed and parallel implementation of the real-time omnidi ...
Springer-Verlag Berlin2015FIR filters for hardware-based real-time multi-band image blending
Yusuf Leblebici, Vladan Popovic
Creating panoramic images has become a popular feature in modern smart phones, tablets, and digital cameras. A user can create a 360 degree field-of-view photograph from only several images. Quality of the resulting image is related to the number of source ...
Spie-Int Soc Optical Engineering2015A Relative Imaging CMOS Image Sensor for High Dynamic Range and High Frame-Rate Machine Vision Imaging Applications
Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Nikola Katic, Radisav Cojbasic
This paper proposes an unconventional image acquisition scheme for machine vision applications, based on detecting ratios of illumination (pixel) intensities. Detecting relative ratios enables capturing the scene features and patterns almost independently ...
Institute of Electrical and Electronics Engineers2015Performance Optimization and FPGA Implementation of Real-Time Tone Mapping
Yusuf Leblebici, Vladan Popovic, Eliéva Arlette Pignat
This brief analyzes the performance of the hardware-based tone mapping operators for compression of high dynamic range images. The bottlenecks of a tone mapping system are determined and a high-performance field programmable gate array (FPGA) implementatio ...
Institute of Electrical and Electronics Engineers2014Reconfigurable Forward Homography Estimation System for Real-Time Applications
Yusuf Leblebici, Vladan Popovic
Image processing and computer vision algorithms extensively use projections, such as homography, as one of the processing steps. Systems for homography calculation usually observe homography as an inverse problem and provide an exact solution. However, the ...
